Oconnor Mary Ellen #44 (API 42-391-30585) is a plugged well in Refugio County, plugged April 22, 2022, last operated by Dolphin Petroleum LP.

The RRC has issued 3 drilling permits between 1977 and 1987, permitted to 6,413 ft.

It was permitted by Amoco Production Company and has since transferred to Dolphin Petroleum LP on the wellbore schedule.

Completion filings report 4 formation tops, including D-1, 5000, Fq-9, 6570.

Its lease has reported 32.2K barrels of oil and 80K mcf of gas since January 1993, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
